Description

Technical Field

[0001] The utility model relates to a spinning box, in particular to a spinning box for a spinning machine. Background Art

[0002] A spinning machine is a mechanical device used for spinning. Its head is a spinning box (also called a spinning head) equipped with spinning wheels. The workpiece is placed on a spindle, which rotates the workpiece. The spinning wheel applies pressure from one side, deforming the workpiece. Therefore, the stability of the spinning wheel is crucial to the workpiece's processing.

[0003] The spinning wheel is mounted on the end of the spinning shaft that protrudes from the spinning box. The spinning shaft is supported by bearings inside the spinning box. These bearings provide axial support for the spinning shaft as it rotates. However, the bearings typically have limited load-bearing capacity, and the balls within them are susceptible to deformation. Therefore, roller bearings, or other high-load-bearing bearings, are often used for axial support. When the spinning wheel applies spinning pressure, it not only bears the axial force from the bearing itself, but also encounters forces in the oblique direction. This causes the spinning shaft to move up and down along the axis of the entire spinning shaft, resulting in reduced stability over time. Summary of the Invention

[0004] The purpose of the utility model is to solve the above-mentioned problems and to provide a spinning box for a spinning machine in which a spinning shaft remains stable and does not shift.

[0017] The following detailed description of embodiments of the present invention's technical solutions is provided in conjunction with the accompanying drawings. The following embodiments are intended solely to more clearly illustrate the present invention's technical solutions, providing numerous specific details to provide a more thorough understanding of the present invention. However, those skilled in the art will appreciate that the present invention can be implemented without one or more of these details. In these examples, some technical features known in the art are not described to avoid confusion with the present invention.

[0018] It should be understood that the present invention can be implemented in different forms and should not be construed as being limited to the embodiments set forth herein. These embodiments are therefore intended only as examples and should not be used to limit the scope of protection of the present invention.

[0019] In addition, it should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this utility model belongs.

[0020] See Figures 1 to 3 The spinning machine utilizes advanced spinning technology to perform spinning on workpieces such as metal pipes and bars. The spinning box B plays a crucial role in this equipment, primarily mounted to the side of the workpiece spindle A1 of the spinning machine A. To achieve optimal spinning results, the spinning box B is precisely positioned at the front end of the spinning frame A3, where the spinning hydraulic motor A2 resides.

[0021] The spinning box B features a unique and ingenious design. Its main body consists of a sturdy and durable housing 1. Inside this housing 1, a spinning shaft 2 is cleverly positioned, providing stable rotational support during the spinning process. To ensure that the spinning shaft 2 can withstand the tremendous spinning pressure, a thrust roller bearing 4 is specifically placed on the shaft. This effectively disperses the pressure during the spinning process, ensuring smooth operation.

[0022] The spinning wheel 3 is cleverly placed on the part of the spinning shaft 2 that is exposed from the spinning box 1. The function of the spinning wheel 3 is to apply pressure to the workpiece during the spinning process, thereby achieving various spinning effects. In order to ensure that the spinning wheel 3 can work stably, a limiting rib 13 is provided in the box body 1, and thrust roller bearings 4 are symmetrically arranged on both sides of the limiting rib 13. The function of these bearings is to provide stable bearing axial support and axial support for the spinning shaft 2, and they also play a role in dispersing the pressure during the spinning process. The spinning shaft 2 passes through the axial hole formed by the limiting rib 13 around the inner wall of the box body, and the thrust roller bearing sleeves on both sides of the axial hole are placed on the spinning shaft 2.

[0023] The entire spinning box A is designed to ensure both structural stability and a smooth spinning process. During operation, the spinning box A accurately completes the spinning task, providing strong technical support for the production of metal pipes, bars, and other industries in my country.

[0024] During implementation, the spinning wheel 3 receives the reaction force of the workpiece and transmits the force to the spinning shaft 2. The spinning shaft 2 is installed inside the box body 1 under the thrust roller bearings 4 symmetrically arranged on both sides of the limiting ribs 13. The spinning shaft can be stabilized under the stronger load of the thrust roller bearings 4 in two symmetrical ways, and the two thrust roller bearings 4 are clamped against the limiting ribs 13, and can also resist the push and pull of the spinning shaft 2 in the up and down directions of its axis from the reaction force, so that the spinning shaft 2 does not move in this direction, thereby ensuring the accuracy of the spinning wheel.

[0025] Furthermore, as an improvement to the present invention, the race 41 of the thrust roller bearing 4 is placed against the side of the limiting rib 13 .

[0026] This arrangement, with the seat ring 41 positioned against the limiting rib 13, not only optimizes the bearing support structure but also enhances the stability of the spun shaft 2 during the spinning process. As the spun shaft 2 rotates, the seat ring 41 clings to the limiting rib 13, forming a robust support system that helps distribute the torque and axial force generated during spinning, thereby protecting the spun shaft 2 from excessive wear.

[0027] Furthermore, as an improvement to the present invention, bearings 5 ​​are respectively sleeved at both ends of the spinning shaft 2 in the box body 1. The bearings are ball bearings, one of spherical roller bearings; and bearing seats are provided between the bearings at both ends and the thrust roller bearing 4 to control the spacing.

[0028] To further enhance the operational performance of the spinning shaft 2, a bearing seat is cleverly positioned between the bearing 5 and the thrust roller bearing 4. This bearing seat is more than just a simple spacer; it also plays a crucial role in adjusting and controlling the spacing between the bearings. Precise adjustment of the bearing seat ensures an optimized distance between the bearing 5 and the thrust roller bearing 4, providing optimal support and reducing friction during the spinning process.

[0029] Furthermore, as an improvement to the present invention, stepped surfaces are provided along the front and rear ends of the housing 1, on which bearings 5 ​​are pressed. These stepped surfaces are used to mount and limit the bearings 5. The bearings 5 ​​are ball bearings, a type of spherical roller bearing, which excel in bearing the rotational load of the spinning shaft 2, ensuring a smooth spinning process.

[0030] A hydraulic chamber 21 is provided in the middle of the spinning shaft 2. The function of the hydraulic chamber 21 is to provide the necessary hydraulic power for the spinning process and ensure the stability of the rotational torque of the spinning shaft 2. At the rear end of the housing 1, a tail cover 11 with an oil delivery hole in the middle presses a sealing ring (not shown) onto the housing 1 and is fixed to the housing 1 as a whole via fasteners 14. A bearing seat 51 is placed between the bearing on the step surface at the rear end and the thrust roller bearing in front of the limiting rib 13. This can effectively control the spacing between the bearings and ensure the stability and durability of the spinning shaft 2 during the rotation process. The front end of the housing 1 is pressed by a front cover 12 to seal the oil seal on the spinning shaft 2 and is fixed to the housing 1 as a whole via fasteners.

[0031] In addition, during implementation, in addition to the bearing and the bearing seat, other sleeve parts that are beneficial to the stability of the spinning shaft 2 can also be sleeved on the spinning shaft 2.

[0032] Furthermore, as an improvement to the present invention, the spinning wheel 3 is mushroom-shaped or dish-shaped.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
